Patent number: 9356397Abstract: A connector and an electronic system using the same. The electronic system (100) comprises a first electronic device (102), a second electronic device (200), and a connector (104), the connector being used for connecting the first electronic device and the second electronic device. The first electronic device has a first plane (P10). The second electronic device has a second plane (P20). The first plane and the second plane are not coplanar. The connector comprises multiple terminals (110, 120, 130), electrically connected to the first plane and the second plane respectively. In the connector, a signal terminal is located between a first ground terminal and a second ground terminal, which is beneficial to transmission of a low-noise high-frequency signal in a shielded environment. The connector and the electronic system using the same may transmit a signal between different planes by connecting junctions in different planes.Type: GrantFiled: January 19, 2012Date of Patent: May 31, 2016Assignee: ASUSTEK COMPUTER INC.Inventors: Chien-Ming Hsu, Kuo-Chu Liao, Chung-Yuan Kuang, Chiuan Jian Huang

Publication number: 20130021757Abstract: A portable electronic system includes a first electronic device, a carrying element and a second electronic device. The first electronic device has a casing. The casing has an accommodating portion located at one side of the casing. The carrying element is connected with the casing and capable of relatively moving between a first position and a second position of the casing. The second electronic device is disposed at the carrying element and coupled to the first electronic device. When the carrying element is located at the first position, the second electronic device is received within the accommodating portion by the carrying element. When the carrying element is located at the second position, the second electronic device is departed from the accommodating portion by the carrying element.Type: ApplicationFiled: July 20, 2012Publication date: January 24, 2013Inventors: Wei-Hsin SHIH, Kuei-Shun Yeh, Chung-Yuan Kuang
